Anyone else hyphenating or using both last names?

Please only respond if you are planning on hyphenating or have used both last names before. We are planning on using my last name and his. First of all I was born in Poland and being the only girl in the only one with my last name so if my child doesn't have it then it will be gone forever so it's a huge deal to me however the last name with both of ours will be 16 letters long! Why did you decide to do it and how has it worked out for you?
